Review: Magical and Colorful - Magical and Colorful! The Barbie Rainbow Mermaid Doll is beautiful! The lights and rainbow tail make playtime magical. My daughter loves it.
Review: Awesome for my daughter - This toy turned out better than I ever could have expected. We were going through all my daughters bath toys and throwing out ones that she had outgrown. I told her she could pick out something new and that’s when I discovered this mermaid toy. As soon as it came my daughter wanted to open it. The packaging was a standard Barbie package. I was able to get it out pretty quickly with just a pair of scissors. Immediately my daughter figured out how to make her tail light up. Different timing of pushing the button makes the tail do different light patterns. The lights are bright and multicolored. That night she took her new mermaid in the bath with her. She did many trips beneath the water while lit up and I was not at all concerned with the lights not working. After taking her out of the bath my daughter continued to play with her. Through many baths and other play times, this Barbie has continued to light up and work better than expected. I would buy time and time again.

## Questions & Answers

**Q: Can this be used as a bath toy?**
A: My daughter received this for Christmas and the very first time she used it in the water it completely stopped working! I feel this is FALSE advertising saying it’s okay to dip in water, but dipping it in water breaks it 😖 a little upset because my daughter loves this Barbie and is so upset she doesn’t light up anymore..

**Q: Can you remove the tail and use as a regular barbie?**
A: No the barbie has no legs. It's all one piece. You do have to attach the fin when arrives.

**Q: The battery is not effected if you put this in the water?**
A: Ours stopped working about a month after we got it. Batteries had corroded/leaked. Replacing the batteries didn't help.

**Q: What size batteries does it take?**
A: what size batteries does it take?

### ⭐⭐⭐⭐⭐ Magical Mermaid Barbie!!!! Perfect for bath time and water play!!!
*by J***Y on February 27, 2023*

I bought this doll originally as a gift. It wasn't going to arrive on time, so I ordered an additional one that did arrive on time. Funny, they both arrived together. Of course my daughter has a mermaid barbie, but not the one that lights up. I was pretty pumped to get both. I was hesitant to let this go in the bath. The father of the girl I gifted it to said that his daughter used it in the tub all the time. So, I let Kendall use hers in the tub!!! This doll is awesome!! It lights up in many patterns under the water with no issue. Has been in the tub several times over the past 2 months and still going strong!!! I've purchased this doll for 2 more girls since my original purchases in December!! Now to level up the gift, I've purchased a rainbow bath bomb to add some extra fun!!!
